How can PHP developers effectively debug and test form submissions to ensure proper array structure?

To effectively debug and test form submissions to ensure proper array structure in PHP, developers can use the `var_dump()` function to inspect the structure of the submitted form data. This allows developers to see the array keys and values and identify any issues with the structure. Additionally, developers can use `isset()` or `empty()` functions to check if specific keys are present in the array. 

// Debugging and testing form submissions for proper array structure
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Using var_dump() to inspect the structure of the form data
    var_dump($_POST);

    // Checking if specific keys are present in the array
    if (isset($_POST['key'])) {
        // Perform actions based on the presence of the key
    }
}
